Ever since the most recent revamp of the site numerous problems have occurred and continue to do so. Sporadically, for some reason having nothing to do with my computer or my browser, this site logs me out. Also, without reason, regardless of how many times I reset this, every single forum re-defaults back to showing only posts from the last 2 weeks. I'm not alone in experiencing these problems. This is becoming very tiresome and needs to be addressed.
I say, that's quite odd. I haven't noticed any glitches associated with the software update (that I remember, at least). But good luck with yours.
It's possible the forum default has been reset to two weeks as apposed to months, since it appears the same for me. Login problems can occur for two reasons: 1: A bug, this is what most people usually suspect. 2: Someones Hijacked your session, To be on the safe side and to make sure that it can't only be reason no. 1, Change your password in your user preferences page, then Log out and then back in again. If you still have problems with the system logging you out, you'll know that it's just a bug which will need addressing.
